This read-create value is a string specifying which DS0 time slots within the identified T1/E1 are assigned to this channel, expressed as a range or list, and can only be set at row creation. It lets an admin fractionally allocate a single T1/E1 into multiple sub-rate circuits by assigning different time slots to different channel rows. For example, an admin sets csChDs3TimeSlots to "1-12" for one customer's fractional T1 service, while a different channel row on the same T1 uses "13-24" for a second customer.
